摘要
哈尔乌素露天煤矿剥离6号煤层顶板岩石到采场中部和南部时,6号煤层突然缺失,经过对现场揭露相关台阶的踏勘、写实、地层对比分析,查明了揭露区6号煤层缺失是由于该区域发育了1条地堑构造所致。通过深入分析,发现该地堑是黑岱沟露天煤矿F3逆断层在哈尔乌素露天煤矿境界内的延伸,并且精补地质报告确定的F3逆断层通过分析认为在黑岱沟露天煤矿境界内亦为地堑,而且发育规模较哈尔乌素露天煤矿大。
On the process of stripping the roof rock in No. 6 coal seam to the middle and southern part of stope,we found the No. 6 coal seam missing suddenly. After the investigation,analysis of stratum of the disclosed benches,we found that the reason for No. 6 coal seam missing is a new graben has formed in this area. With deep analysis,we found this graben is the F3 reverse fault of Heidaigou Open- pit Mine extending to Haerwusu Open- pit Mine,and then we accurately complement the geological report relating to the F3 reverse fault. By the analysis of this essay,we believed that the area in the Heidaigou Open- pit mine is also graben,with larger area than the one in Haerwusu Open- pit Mine.
